Questions about my Hooker LTs
Curious how two headers connect into one. Do they weld to the cat or do they bolt onto the cat? Never installed headers on anything with more than 4 cylinders.

the headers will come down off the motor then end. you can either get a catted ypipe or off road one. it connects the two headers together with a smooth flowing junction and ends where the intermediate pipe starts(where a catback or stock exhaust begins).

So you mean it cant connect to my stock exhaust? I plan to get hooker catback later on.

yes you can hook it up to the stock exhaust. the ypipe should end where the stock one did.

some also run true duals, one pipe for each side, usually with a connecting pipe at some point... something else to think about

Well I was told I need the extension O2s and the pacesetter Y pipe. What are you talking about?

you have 4 o2 sensors on your vehicle.... the front two screw into usually the collector of the header and sense the air/fuel mixture of unburnt gasses
the rear o2 sensors sense how well your catalytic converters work
that being said, the front two are absolutely necesary, an will alot of times need an extension on the wiring harness....
the rears can be deleted, this if for if you are going to be going without catalytic converters, if you delete your cats and still run rear o2's you will throw engine codes possibly putting your car into limp mode.... to delete them you can either get a tuner to erase their reading, or get simulators that go on the end of the harness and do just that, simulate that the o2 is working great... another option that will also work is to just zip tie them up so they aren't dragging yet are reading ambient air that is "cleaner" than the air the front o2s are reading...

So I know about the extensions for the first 2. The rear two that go to my cat I can just zip tie where? Anywhere that wont drag? Still throw codes?
